FAQ

What is the significance of the ‘J’ suffix in the FYH UCF311J model number?
The ‘J’ suffix in FYH bearing units typically indicates that the unit is fitted with a standard set screw locking mechanism and a J-type pressed steel slinger for dust protection. This is the most common configuration for general industrial applications.

What is the correct lubrication procedure for this UCF311J bearing unit?
The FYH UCF311J comes pre-lubricated with a high-quality lithium-based grease suitable for a wide range of operating conditions. It features a grease nipple for relubrication. The relubrication interval depends on the operating speed, load, and environmental conditions. Refer to the FYH engineering manual for specific interval calculations.

Can the UC311 insert bearing be replaced separately from the F311 housing?
Yes, the FYH system is modular. The UC311 insert bearing can be purchased separately and replaced within the F311 cast iron housing. This can be a cost-effective solution for maintenance, as you do not need to replace the entire unit if only the bearing is worn.
